Hello, not sure you understand correctly, but you seem to write that what you did on one account affected another account which has nothing to do with what you did? Maybe then log out, completely empty your browser and site caches and reconnect?
I couldn’t figure out why that would have anything to do with it either but that was the last thing I did when the problem started. I have logged out and cleared the cache several times and log back in it. I still have the same problem. I’ve tried it on multiple test accounts.
